Mallory is holding the box of chocolates as she eats them when Bud & Coyote walk in. When Mallory call Coyote "Broseph" her hands are behind her back. The scene right after that, Mallory is holding the box again.
Mallory & Robert are both wearing a lighter colored button up shirt under their blue sweater.
In the kitchen the cake has a small portion of chocolate on top in the middle. While everyone is eating cake in the dining room, there is a lot more chocolate top of the cake.
There are a lot more strawberries on the cake at the dining table than there were when Bud carried it out of the kitchen.
Strawberries appear, disappear, & reappear on the cake while Brianna & Bud talk in the kitchen.
